Interface · `import type { Quat } from '@holostep-configurators/runtime-client/contract';` · stable · since 2.0.0 · section 1. Basics

Unit quaternion. As input its components are finite and its length is 1 within 1e-3, and the
runtime normalises it; another one, a zero one included, is invalid input (spec section 3.4).

## Members

| Member | Kind | Summary |
| --- | --- | --- |
| <a id="x"></a>[`x`](Quat.x.md) | property | Vector part, X. |
| <a id="y"></a>[`y`](Quat.y.md) | property | Vector part, Y. |
| <a id="z"></a>[`z`](Quat.z.md) | property | Vector part, Z. |
| <a id="w"></a>[`w`](Quat.w.md) | property | Scalar part; 1 with x = y = z = 0 is no rotation. |

## Declaration

```ts
export interface Quat {
  x: number;
  y: number;
  z: number;
  w: number;
}
```

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `Quat` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | not recorded: no ledger row names this member or its owner |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
